For a completely disconnected network, I don't care what you do,
use whatever number you want. There's no need to coordinate that
with the internet in any way.

For a network connected to a connected network, either get GUA from
an RIR or get GUA from the network you are connected to or get
GUA from some other ISP/LIR.

There are lots of options.

I'd like to see RIR issued GUA get a lot cheaper. I'd much rather see
cheap easy to get RIR issued GUA than see ULA get widespread use.
